(Reuters) – Researchers in Canada have identified a new type of vaping-related lung injury that they believe is linked to sweeteners in traditional vape pens and that they cause symptoms similar to "popcorn lungs" injury to workers exposed to sweeteners in microwave popcorn.
The case, published in the Canadian Medical Association Magazine on Thursday, belonged to a 17-year-old man who developed a form of bronchiolitis with severe and irreversible lung damage from chemical exposure.
This was attributed to diacetyl, a chemical which is a known cause of bronchiolitis, which gives the buttered flavor of microwave popcorn. In various studies, diacetyl has also been found in vaporized liquids.
A healthy young Canadian came to the emergency room of a public hospital in Ontario last spring with a severe cough. She was diagnosed with pneumonia and prescribed antibiotics.
Five days later, he returned with worsening symptoms and was accepted and given intravenous antibiotics. It continued to fall and a mechanical ventilator was installed, but it still did not improve.
At this point, he was transferred to the London Center for Health Sciences and applied a non-machine ECMO extra-machine extracorporeal membrane oxygenation, an extreme treatment that inherited the work of the lungs. This stabilized him but did not reverse the situation.
He is a London Health Intensive Care Doctor and a study author. "I was worried that his lungs would never heal enough to get him out of the machine," Karen Bosma said.
Fearing that he might need a lung transplant, the team transferred young people to a regional transplant center in Toronto. As the tests ruled out the infection, doctors decided to try high-dose steroids, which helped to reduce inflammation.
The patient reported that he was using both the flavored nicotine cavities and the psychoactive substance of marijuana, THC. Doctors even suspected a vaping injury even before the US outbreak was reported.
Although this case is similar to more than 2,000 cases of vaping-related disease in the United States, the injury is different. Instead of a damaged air sac in the lungs, it damaged the airways, which the doctors of the young doctor believed were caused by chemical injuries.
"This is a new finding." Said.
It can be said that several vaping chemicals may cause injury, but the team concentrated on diacetyl because it caused similar diseases.
Four months after discharge, the young man still has trouble breathing. Bosma, it's not clear whether your lungs will heal.
"Popcorn is irreversible in lung patients."
